  • This is a case of the core reamer breakage during anterior cruciate ligament reconstruction using bone-patellar tendon-bone autograft. A 19-year-old man with acute anterior cruciate ligament rupture had reconstruction surgery. During tunneling in the proximal tibia, the core reamer have been cracked open and broken. Rest of the procedure was performed routinely except the tibial sided fixation of bone block which was performed with larger interference screw than usual. The patient followed the accelerated rehabilitation program. The result was satisfactory at 2 years after surgery.

  • Achilles tendon rupture is a common sports injury encountered in younger populations. Various treatment methods are used for acute and chronic rupture. Several treatments for each condition are available, each having their advantages and disadvantages. In an acute rupture, surgical treatment may be a priority for younger patients or those wishing a quick return to play, but the long-term functional outcome is similar to non-surgical treatment. In addition, the re-rupture rate shows a slight difference between the two treatments. The clinical outcomes are similar regardless of the surgical treatment, but an accelerated rehabilitation program should be accompanied by good results. In chronic and neglected rupture, surgical treatment is preferred over non-surgical treatment. Treatments are chosen based on the size of the tendon defect. This article reviews the current updates in the treatment of Achilles tendon rupture that will help clinicians choose the appropriate treatment.

  • The incidence of Achilles tendon rupture is increasing as more people participate in sports and physical activities. However, whether to treat a complete rupture of the Achilles tendon, conservatively or operatively, is still controversial. Current studies show that the nonoperative treatment of acute Achilles tendon rupture with short-term immobilization for up to two weeks and subsequent accelerated functional rehabilitation with protected weight-bearing results in similar functional outcomes and re-rupture rates compared to those treated surgically. Also, nonoperative treatment does not risk any surgical morbidity such as wound problems, infection, and nerve injury. Therefore, the treatment options for acute Achilles tendon rupture should be carefully chosen in consultation with patients regarding possible clinical outcomes and complications of both treatment options.

  • 북한의 황폐산림 양상을 살펴보면 시기별 북한 내 정치 사회 경제적인 여건과 밀접한 관계를 맺으면서 변화해 왔음을 알 수 있다. 일반주민들에 의한 생존형 산림훼손은 1990년대 사회주의권의 붕괴와 수년에 걸친 자연재해로 인해 경제난이 심각해지고 중앙집권적 계획경제 체제가 붕괴되면서 가속화되었다. 계획경제 체제에서의 배급제가 붕괴되면서 주민들은 식량을 확보하기 위한 수단으로 산지를 무분별하게 개간하였고, 땔감을 확보하기 위해 나무를 남벌하였다. 국가 기관들도 외화를 획득하기 위해 수출용 목재 벌채량을 늘리면서 북한 산림은 빠른 속도로 황폐화 되었다. 산림황폐화로 인한 피해가 확대되면서 북한은 결국 산림복구를 위한 자구책을 마련하는 한편 국제사회에 산림복구 지원을 요청하였다. 이에 남한 민간단체도 조림용 묘목생산의 기반인 양묘장 건설을 위주로 하는 물적 지원 사업을 시작하였다. 그러나 앞으로의 북한 산림복구 지원은 현재와 같은 단순한 물적 지원을 벗어나 1970년대 남한의 치산녹화 성공 경험을 토대로 다음과 같은 북한의 경제사회적 여건을 고려한 황폐산림복구 기본방향을 설정하고 체계적으로 추진하는 것이 필요하다. 첫째, 2000년 이후 북한의 중앙집권적 계획경제 체제가 붕괴된 이후 조성되고 있는 지방, 기업, 노동자간 다양한 이해관계를 고려한 산림복구지원이 이루어져야 한다. 두 번째, 장기간 주민들의 적극적인 참여가 요구되는 산림복구 사업의 특성상 산림복구 현장에서 경제적 이익을 얻을 수 있도록 하여 주민들의 자발적인 참여도를 높이도록 해야 한다. 세 번째, 산림복구 사업과 병행하여 농산촌 종합개발 사업을 연계하여 주민들의 산림의존도를 낮춰가는 것이 필요하다. 네 번째, 기존의 북한 산림관리 시스템을 활용하여 단기간 대규모 집중 조림에 필요한 노동력과 행정력을 확보하는 한편, 산림복구 이후의 산림관리를 체계적으로 담당할 수 있는 시스템의 개선도 함께 진행되어야 한다.

  • This study was performed to investigate the surface properties and in vitro biocompatibility of electrochemically oxidized Ti-6Al-7Nb alloy by anodic spark discharge technique. Discs of Ti-6Al-7Nb alloy of 20 mm in diameter and 2 mm in thickness were polished sequentially from #300 to 1000 SiC paper, ultrasonically washed with acetone and distilled water for 5 min, and dried in an oven at $50^{\circ}C$ for 24 hours. Anodizing was performed using a regulated DC power supply. The applied voltages were given at 240, 280, 320, and 360 V and current density of $30mA/cm^2$. Hydrothermal treatment was conducted by high pressure steam at $300^{\circ}C$ for 2 hours using a autoclave. Samples were soaked in the Hanks' solution with pH 7.4 at $36.5^{\circ}C$ during 30 days. The results obtained were summarized as follows; 1. The oxide films were porous with pore size of $1{\sim}5{\mu}m$. The size of micropores increased with increasing the spark forming voltage. 2. The main crystal structure of the anodic oxide film was anatase type as analyzed with thin-film X-ray diffractometery. 3. Needle-like hydroxyapatite (HA) crystals were observed on anodic oxide films after hydrothermal treatment at $300^{\circ}C$ for 2 hours. The precipitation of HA crystals was accelerated with increasing the spark forming voltage. 4. The precipitation of the fine asperity-like HA crystals were observed after being immersed in Hanks' solution at $37^{\circ}C$. The precipitation of HA crystals was accelerated with increasing the spark forming voltage and the time of immersion in Hanks' solution. 5. The Ca/P ratio of the precipitated HA layer was equivalent to that of HA crystal as increasing the spark forming voltage and the time of immersion in Hanks' solution.

  • 고속도로에서 재령이 20년이 넘는 노후 콘크리트가 늘어남에 따라 콘크리트 포장의 보수/보강이 중요한 이슈로 대두되고 있다. 노후 콘크리트 포장의 보강 대안으로서 아스팔트 덧씌우기가 많이 사용되고 있으나 반사균열 및 포트홀 등 체류수로 인한 문제가 심각하게 대두되고 있다. 본 연구는 반사균열 및 체류수의 문제를 최소화하기 위해 고안된 접착식 방수층을 소개하였으며 포장가속시험을 통해 일반 택코팅을 적용한 합성단면포장과 비교평가를 실시하였다. 실험은 강우를 모사하기 위해 물을 뿌리면서 진행하였고 덧씌우기 포장체의 거동 및 수분 저항 특성을 분석하였다. 연구결과 접착식 방수층은 아스팔트 포장과 콘크리트 포장이 일체로 거동하는 것을 도와주기 때문에 아스팔트 포장체에 발생하는 거동이 일반 택코팅 구간과 완전히 다른 것으로 나타났다. 또 수분의 유입을 최소화하므로 결과적으로 반사균열의 발생을 약 70% 지연시키는 것으로 나타났으며, 체류수로 인한 손상도 줄여주는 것으로 나타났다.

  • Abnormal regulation of glucose and impaired lipid metabolism that result from a defective or deficient insulin are the key etiological factor in type 2 diabetes mellitus (T2DM). The our study evaluated the beneficial effect of diet supplementation with Lentinus edodes on hyperglycemia and lipid metabolism in normal and type 2 diabetic rats. The animals were divided into 4 groups: group I(control) rats were fed standard diet (12% of calories as fat); group II (T2DM) rats were fed HFD (40% of calories as fat) for 2 weeks and then injected with STZ (50 mg/kg); group III and group IV rats were continually fed a diet containing 1% and 10% Lentinus edodes for 4 weeks after T2DM induction, respectively. After 4 weeks we determined biochemical parameters such as glucose, insulin concentration, serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), and glycosylated hemoglobin (HbA1c) concentration were also measured. There was a significant reduction in serum TC and TG in the Lentinus edodes supplement groups. The Lentinus edodes diet supplementation were found to have a potent lipid metabolism improvement as well as LDL concentration decreased and HDL concentration was increased. Concentrations of blood glucose and HbA1c in the experimental groups II were significantly decreased after 4 weeks compared with the control group. The Lentinus edodes diet supplementation is useful in regulating the glucose level, improves the insulin, HbA1c, serum lipid metabolism in experimental diabetic rats. We suggest that Lentinus edodes supplementation may have the control effects of diabetes mellitus by improving blood glucose control and lipid metabolism.

  • Objectives: This study was conducted to evaluate the hair growth-promoting effects by Rumex japonicas Houttuyn ethanol extract (RJHEE) in C57BL/6N mice and HaCaT cells. Methods: The hair growth effect was examined by topical application of RJHEE on the shaved dorsal skin of C57BL/6 mice. Six-week old mice were depilated and separated in 4 groups; CON (vehicle treatment), MXD (2% Minoxidil), and RJHEE (2% and 4%). The treatments were applied daily for 17 days. The hair growth was determined photographically and the hair density, thickness and length were identified by Folliscope. In dorsal skin tissue, the expression of hair growth-related protein was analyzed by Western blotting. In HaCaT cells, the cell proliferation and the protection against H2O2-induced cell damage by RJHEE were analyzed. Results: Our results indicate that RJHEE promote the hair growth, hair density, thickness and length. RHE activate the Wnt/𝛽-catenin signaling and induced the expression of cell survival-related proteins, such as pERK/ERK and Bcl-2/Bax. In HaCaT, RJHEE accelerated the cell proliferation and protected the H2O2-induced cell damage. Conclusions: Our results strongly suggest that RJHEE promotes hair growth by regulating the activation of Wnt/𝛽-catenin signaling and cell survival signaling and protects oxidative stress-induced hair damage. Therefore, RJHEE has a hair growth activity and can be useful for the treatment of alopecia.
